A nurse is providing vehicle safety education to the parents of a premature newborn.
Which of the following statements should the nurse include in the teaching?

The nurse should further evaluate respiratory characteristics and muscle tone to determine if the newborn is experiencing a complication.

Rationale for correct answers
Respiratory characteristics are critical to assess because irregular and shallow breathing in a newborn can indicate neurological or respiratory dysfunction. Normal neonatal respiratory rate ranges from 30 to 60 breaths per minute with regular pattern; deviations may signal distress or central nervous system issues. Muscle tone evaluation is essential since increased tone with tremors suggests possible neurologic irritability or withdrawal. Normal newborn muscle tone should be moderate, neither hypotonic nor hypertonic, with symmetrical movement. These signs correlate with the high-pitched cry, tremors, and exaggerated reflexes noted, which may indicate neurological complications such as withdrawal syndrome or hypoxic-ischemic encephalopathy.

Rationale for incorrect answers
Heart rate (A) is important but was not reported abnormal; normal neonatal heart rate ranges from 120 to 160 beats per minute and the absence of murmurs suggests no cardiac compromise. Temperature (C) is less urgent as mucous membranes are moist and skin warm and dry, indicating stable thermoregulation; normal newborn temperature is 36.5–37.5°C. Feeding patterns (D) appear adequate with no difficulty reported, making this less immediately concerning.

Rationale for incorrect answers
Moro reflex (A) and Babinski reflex (B) are both present and exaggerated, which may be reactive but less specific for immediate concern than muscle tone abnormalities. Skin color (D) is normal without cyanosis or jaundice, reducing the likelihood of hypoxia or hemolytic issues.

Take home points

• Respiratory pattern irregularities in newborns may indicate neurological or respiratory dysfunction.
• Abnormal muscle tone and tremors are key signs of potential neurological complications.
• Normal heart rate, temperature, feeding, and skin color reduce likelihood of cardiac or systemic illness.
• Reflex exaggeration alone is less specific than muscle tone and respiratory changes for early complication detection.

Choice A rationale

Polyuria, an abnormally large production of urine, is not a typical adverse effect of epidural analgesia. Epidural analgesia, due to its influence on sympathetic nervous system blockade, can sometimes lead to urinary retention by inhibiting bladder detrusor muscle contraction and relaxing the urethral sphincter. Therefore, polyuria would be an unexpected finding.

Choice B rationale

A maternal temperature of 37.4° C (99.4° F) is within the normal physiological range for a laboring client. Slight elevations can occur due to the metabolic demands of labor or dehydration, but this temperature does not indicate an adverse effect directly attributable to epidural analgesia. Fever, defined as a temperature above 38° C (100.4° F), can be associated with epidural use due to thermoregulatory changes.

Choice C rationale

A fetal heart rate of 152/min is within the normal range for a term fetus, typically 110-160 beats per minute. This finding indicates a healthy fetal response and does not suggest an adverse effect of epidural analgesia. Epidural analgesia itself usually does not directly alter the fetal heart rate in a negative way if maternal hemodynamics remain stable.

Choice D rationale

Hypotension is a common adverse effect of epidural analgesia. It occurs due to sympathetic blockade, which causes vasodilation and peripheral pooling of blood, leading to decreased venous return to the heart and a subsequent drop in cardiac output and blood pressure. This reduction in blood pressure can compromise uteroplacental perfusion.
